Help: Damage increase through aura

[BadWolf]

I need help,

I am trying to make an ability that increases damage per level but i cant
seem to add damage, only a % of damage. Is there any way to add damage
without it being a % of damage?

Thanks In Advance (if its possible)

Orc war Drum ability has the line flat bonus - false. Turn it to true and you get it as a flat bonus instead of % ^^
